Lisa Robin Kelly Autopsy Results Reveal Heavy Drug Use

The 43-year old's boyfriend and estranged husband went back and forth over who was to blame for Kelly's death, which was initially reported to be the result of an embolism.

But the autopsy from the Los Angeles County coroner's office has now come in for the That 70s Show star and it confirms she died from multiple drug intoxication.

Few other details are available, but authorities say the fatal intoxication took place by oral ingestion - and that the manner of death was accidental.

Kelly portrayed Laurie Forman on the aforementioned sitcom from 1998-2006.

She had been arrested several times prior to her passing, having faces charges over the years that stemmed from drunk driving to domestic assault.

But she has voluntarily checked herself into a rehab facility just a couple days before she overdosed.

Said Kelly's agent soon after the sad news broke last year: “I spoke to her on Monday and she was hopeful and confident, looking forward to putting this part of her life behind her. Last night she lost the battle.”
